The child_process.spawnSync() method is generally identical to spawn with the exception that the function will not return
until the child process has fully closed. When a timeout has been encountered
and killSignal is sent, the method won't return until the process has
completely exited. If the process intercepts and handles the SIGTERM signal
and doesn't exit, the parent process will wait until the child process has
exited.
If the shell option is enabled, do not pass unsanitized user input to thisfunction. Any input containing shell metacharacters may be used to triggerarbitrary command execution.
